To alt whom/it may concern.-

Be it known that we, PAUL JONES, of Coeymans, in the county of Albany and State of Will .011:- V V -y. Flgure I is a side elevation of a machine embodying our invention in proper condition isa side elevation of the brnsh-operating and New York, and JOHN E. BURLINGHAM, of New Baltimore, in the county of Greene and State of New York, have invented new and useful Improvements in Street-Swee'1)ing Machines, of which the following is a specification, reference being bad to the'accompanying drawings, which form part of this specification, in

for sweeping. Fig. 2 is a plan view of the same. Fig. 3 1s a rear elevation; and Fig. 4

dirt-elevating mechanisms detached from the dirt-cart on which the.v forward part of said,

mechanism-is borne.

Our invention relates to a street-sweeping machine, which comprises a dirt-cart onjwhich the forward part of the mechanism for sweepin g and elevating the dirt is borne, and which is detachable from said mechanism, so as to be'ntilized for the removal-of the dirt to a dumping-ground and the o 7 feet ofbnr inven tion is atO combine in, one'ccnstrnction the means for sweeping the street and carrying away the dirt collected therefrom.

As represented in the drawings, A designates a dirt-cart of any ordinary construction, excepting that each of its Wheels 1 is provided with a sprocket-wheel 2, which is preferably cured to the hub of said cart-wheel. so as to rotate therewith.

" B is the frame-Work for thesweeping-brnsh and dirt-elevating mechanisms; Said frame is n detachably connected-to the dirt-cart A by means of a pair of armsiwhich extend along the oppositesides of thedirtreceptacle of said cart, and aresecnredtheretc by means of hasps 4 or other suitable fastenings, which can be readily unfastened to release the cart H "from said frame-work. The rearwardpart of the latter is provided with a trailing wheel 0, which is journaled in the outer end of the rearwardly-bcnt bifurcated arm D. The innor end of said arm is provided with a vertical pivot 5, which is fitted to revolve and to slide vertically in a bearing 6,, fixed on said 1390 Serial N0.343 .322. (No mode" frame-work. The center line of the axis of the trailing wheel 0 and the center line of: the pivot 5 are arranged eccentrically to each chine may be moved. The pivot 5 is provided with a circumferential flange 7, on which frame-work and its attached parts will bear Whenever'the .sw

eration. Said'flange is also fitted to receive the pressure from an eccentric 8, which is when preferred, a pairof said eccentrics may be, arranged at oppositesides of said bearing to bear on said flange. By turning ,said ecupon said fiange the rear-War end of the machine may be raised to keep the brush from the surface of the street, and thereby the.

it may be turned on, its pivotal center, and said arm is connected to an operating-rodlO,

'by'the driver of the machine when occasion requires. T i v .1

The framework B 1s provided with an adits equivalent should be arranged to carry the weight of the forward part of said tram e-work and. i ls.lattachcd mechanism Whenever. the

dirt-cart A is detached therefroin; lint yvlien connected by adjusting-screws ld with like other, so that the trailing wheel 0 will be a.

tomatieally deflected to correspond to the;

eephrgmeichahismis in opcentries so as to bring the lar er side to bear sides of the frame-work B. Said bearings are t5 conrse--straight or (16VlOl1S-1I1 whlchthe ma the weight of the rearward portion ofthe pivoted to the bearing, 6 for the pivot 5, and,

sweeping mechanism can be rendered inop- 3 erative whenever occasion may reqnir'e- Each 1 eccentric 8 isprovided with an arm 9, by'which "7 5 by whichsaid eccentrics can be manipulated H justable strut 11,0r which there should beone I at each side of the machine, and said strut or said dirt-cart-is attached. to the framework naled in theb'earings 16. Said shaft has a sprocket wheel 21 secured thereto. Saidsprocket-wheel is connected by means .of an endless chain 22 withthe sprpcket-wheel 2, so as to impart the requiredrotatory motion to the brush E.

l? designates the dirt elevator or conveyor, which consists of an endless belt or belts provided with buckets 23, by which the dirt deli/irered by the brush E into said buckets is automatically deposited into the box or dirt receptacle of the cart A. Said elevator has its motion imparted thereto by'means of an endless chain 24, which engages with the sprocketwheel 2, which is attached to the wheel 1 on the opposite side of the cart A to the one which imparts motion to the endless chain 22. The latter connects with a sprocketwheel 25, which is secured to a shaft 26, journaled' in the upper part of the frame-work B. Said shaft also carries a drurn27, which is located to lie directly over the after part of the box of the cart A, so that the dirt. delivered from the elevator-buckets will fall directly into the box of said cart. From the drum 27 the endless belt of the elevator passesever'a pair of pulleys 28, which are secured to a shaft 29 and are spaced apart sufii'ciently to allowthe length of the buckets 23 to pass between them.

From the pulleys 28 the elevator-belt passes downwardly and under a drum 30, thence upwafdly to the drum 31, from whence it passes to and over the upper side of the drum 2?.

The drum 30 is journalcd in the lower end of a pair of pendulous arms 32, whose upper end is pivoted, as at 83, to the frame-work B. The lower end of said arms is provided with a journal-box 34, which is adjust-able thereon so as to produce an equal strain on both edges of the elevator-belt. The drum 30 is arranged in advance of but in proximity to the brush.

1, so that the dirt that is swept up by said brush will be delivered into the buckets 23 of, the elevator. The drum 31 is journaled in the upper part of the rearward side of the frame-work B, but on a lower plane than the journals of the drum 27, so that the elevatorbelt will'be carried on an inclined line from the drum 31 to the drum 27, thereby avoiding the escape of the dirt from the buckets. The

strut 11 is pivotedas. at 35, to the framework B, and hooks 36 or other fastenings are provided for holding said strut in itsraised I position;

Our invention operates in the following manner: The dirt-cart A and frame-work B being secured together, and the endless chains 22 and 24 being engaged on the sprocket- Whe'els respectively assigned to them, then as brush E will be rotated and the dirt-elevator F will be set in motion, so that its buckets 23 will-successively be brought into position in front of the brush E, Where they will receive "and removed to anyrequired place with but slight interruption to theoperation, another dirt-cart is substituted for the one removed, the endless chains are connected to the sprocket-wheels, and the machine is ready for a continuance of its operation.

the machine is drawn over the roadway the By constructing the buckets 23 of the dirt-v elevator F of the same length as the revolving brush Ezwe are enabled to deliv'erthe dirt swept bysaid brush directly into said buckets, and by providing independent driving mechanisms for said elevator and brush we are enabled. to rotate the latter, when required to effect a loosening up of the com-- pacted dirt, Without operating the elevator.

What we claim as our invention, and desire a I to secure by Letters Patent,is-

1 The combination, with afrainework provided with sweeping and elevating mechan-' isms,of a trailing wheel pivoted to said frame- WOlk by means of a pivot provided with a circumferen-tial fiange, and an eccentric fitted to bear upon said flange and secured to a shaft journaled in said frame-work, said shaft being provided with an arm by. which said eccentric can be operated to raise and lower the rear end of said frame-work, as and for the purpose herein specified,
